High speed feed rate on first layer setup

My printer EEProm settings are set for a maximum z speed of 600mm/s.
When I use Prusa Slicr, I get gcodes moving z at 7800mm/s
The printer responds to this and moves up from zero to the first layer height very rapidly. sometime the z is messed up, I think because it may be missing steps.
here is the code offending code is on the last line

; external perimeters extrusion width = 0.45mm
; perimeters extrusion width = 0.45mm
; infill extrusion width = 0.45mm
; solid infill extrusion width = 0.45mm
; top infill extrusion width = 0.40mm
; first layer extrusion width = 0.40mm

M109 S210 ; set temperature and wait for it to be reached

M82 ; use absolute distances for extrusion

How do you change the gcode produced by slicr in start up gcode?
